Housed in a 31 mm round Oyster case, this Datejust 31 features a monobloc middle case, solid case back, and a screw-down winding crown equipped with the Twinlock double waterproofness system, delivering water resistance to 100 metres / 330 feet. The scratch-resistant sapphire crystal incorporates a Cyclops lens over the date window, while the diamond-set bezel adds an unmistakable layer of brilliance to the Everose Rolesor construction.
The chocolate dial presents Roman numeral hour markers alongside centre hour, minute, and seconds hands, with an instantaneous date display and stop-seconds for precise time setting. Powering the watch is Rolex Caliber 2236 — a perpetual, mechanical, self-winding movement featuring a Syloxi silicon hairspring with patented geometry, high-performance Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, a precision rating of -2/+2 seconds per day after casing, and a power reserve of approximately 55 hours. The movement is COSC certified.
The watch rides on an Oyster bracelet in Everose Rolesor, constructed from three-piece solid links and secured by a folding Oysterclasp with an Easylink 5 mm comfort extension link for a versatile, refined fit.
